发明名称 Pouch pack for tobacco as well as a process and apparatus for making this
摘要 In pouch packs for tobacco or the like of the "side-folding pouch" type, it is difficult to make a hermetic closure for the orifice of a pocket of the pouch pack, because accumulations of material impeding the provision of a closing seam or the like arise in the edge regions as a result of the construction of the pack. For this reason, the pouch pack is spread out to the full width of the blank in the region of the orifice for the provision of a closing seam, the closing seam is then made and the projecting lengths of material thus formed in the region of a covering tab are folded over inwards against the latter. This results in a pouch pack which is closed in an absolutely leak-proof manner and which has an essentially cuboid shape after completion.
